- Ex Tax: £30.00
An impedance transformer (49:1) to feed a high impedance, end fed half wave wire which is likely to be a few hundred ohms, and transform it into something closer to a 50Ω (unbalanced) coaxial input. 10 watts
This is a unun ( unbalanced to unbalanced ) transmission line transformer designed to match 3200Ω to 50Ω .
It has a constant impedance transformation ratio of 49:1 from 1.81 MHz to 30MHz. The efficiency is 98 percent.
